I was reading the PII-955 reviews today and I enjoyed this one as well, thanks for the review. I have a couple of comments.

- I think the comparison of DDR3 and DDR2 on a Q9550 is not very useful. Q9550 does not have a memory controller. It connects to the north bridge to access memory via quad-pumped 333MHz bus. As long as both memories can saturate this bandwidth, DDR3 will be slower (or at most equal) due to higher latency of DDR3 than DDR2. DDR3 advantage can only be enabling higher 1:1 FSB for overclocking.
- If you can add a i7-920 with dual-channel memory configuration (instead of triple-channel) that would be very interesting to compare with PII-955, IMHO. Many reviewers do not even mention that i7-920 works with dual-channel configuration perfectly fine at an almost same performance level compared to triple channel and i7 system cost will be a little lower. Triple channel gives a very nice advantage for expanding the memory later by adding only one stick (of the same specs) without any performance penalty (actually performance bonus).

Thanks again
